    Condensin controls recruitment of RNA polymerase II to achieve nematode X-chromosome dosage compensation

    William S Kruesi, Leighton J Core ... Barbara J Meyer
    C. elegans equalizes the expression of X-chromosome genes between the sexes by reducing the recruitment of RNA polymerase II to promoters of X-linked genes in hermaphrodites, using a chromosome-restructuring complex called condensin.

    Laminin signals initiate the reciprocal loop that informs breast-specific gene expression and homeostasis by activating NO, p53 and microRNAs

    Saori Furuta, Gang Ren ... Mina J Bissell
    Endogenous laminins are necessary to build a functional acinus via generating NO, activating p53, HOXD10 and other positive players, but tumor cells neither make laminin nor generate NO, unless they are reverted to an organized structure.

    Inflammation drives alternative first exon usage to regulate immune genes including a novel iron-regulated isoform of Aim2

    Elektra K Robinson, Pratibha Jagannatha ... Susan Carpenter
    Alternative first exon usage was the major event observed in macrophages during inflammation, which resulted in the elucidation of a novel isoform and regulatory mechanism of the protein-coding gene, Aim2.

    The nucleosomal barrier to promoter escape by RNA polymerase II is overcome by the chromatin remodeler Chd1

    Peter J Skene, Aaron E Hernandez ... Steven Henikoff
    The ATP-dependent chromatin remodeler Chd1 controls nucleosome turnover to allow RNA Polymerase to transcribe in vivo.

    Isobaric crosslinking mass spectrometry technology for studying conformational and structural changes in proteins and complexes

    Jie Luo, Jeff Ranish
    A novel pair of isobaric crosslinking reagents is described, which allow relative quantification of crosslinker-modified peptides during mass spectrometry analysis for comparative structural studies of proteins and protein complexes.

    A Notch-dependent transcriptional mechanism controls expression of temporal patterning factors in Drosophila medulla

    Alokananda Ray, Xin Li
    Cell-cycle-dependent Notch signaling cooperates with temporal transcription factors to promote the progression of the temporal transcription factor cascade in Drosophila medulla neuroblasts.

    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon, Sarah E Lower ... Jing-Ke Weng
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    TWIST1 and chromatin regulatory proteins interact to guide neural crest cell differentiation

    Xiaochen Fan, V Pragathi Masamsetti ... Patrick PL Tam
    Network propagation connects TWIST1 with epigenetic regulators CHD7, CHD8, and WHSC1, which collectively promote the bias toward neural crest while suppressing neural stem cell programmes, and subsequently enhance ectomesenchyme potential.

    Compact and highly active next-generation libraries for CRISPR-mediated gene repression and activation

    Max A Horlbeck, Luke A Gilbert ... Jonathan S Weissman
    Integrated modeling of sgRNA positioning, chromatin accessibility, and sequence features enables accurate prediction of effective target sites for CRISPR-mediated transcriptional modulation and design of highly active libraries for genome-scale genetic screens.

    The MADS-box transcription factor PHERES1 controls imprinting in the endosperm by binding to domesticated transposons

    Rita A Batista, Jordi Moreno-Romero ... Claudia Köhler
    Jumping of transposable elements provides DNA-binding sites for the MADS-box transcription factor PHERES1, allowing the regulation of imprinted genes and other key endosperm development genes.
